Abstract

Pioneer plants are found in the former limestone mining area, and there are bacteria in their root systems. These bacteria can be used as biofertilizers. This study aims to find out the use of indigenous PGPR in ex-mining limestone land to be able to increase the yield of pea (Arachis hypogaea L.) var. Tuban. This research was an experimental study with 5 treatments applying indigenous PGPR at concentrations of 0%, 25%, 50%, 75%, and 100% and consist of 5 replications. Stages of research include planting peanuts (Arachis hypogaea L.) var. Tuban by adding indigenous PGPR with the same dose and source in an environment with sufficient sunlight. The parameters observed were biomass, pithy weight, empty pod weight, wet weight, dry weight, pH, and temperature of the planting medium for peanuts. In this study, the results showed that the concentration of PGPR 25% had a significant effect on the dry weight of peanuts and doesn’t had significant effect on biomass. Meanwhile, the provision of PGPR with different concentrations did not have a significant effect on the temperature and pH of the lime mining soil planting media

Abstract

The compost of inked paper and vegetable waste mixture is a result of the process of degradation of the components of lignin and cellulose. The process was activated by cellulolytic bacteria from rumen liquor. The aim of this study to know the compost quality of the inked paper and vegetable waste mixture. The content of by-products of compost studied were the levels of N, P, K, and Pb heavy metals. The composting process in this study was carried out by anaerobic. The N test used the Kjeldahl method, the P and K test used the Bray 1 method, and the Pb test used the AAS method (Atomic Adsorption Spectrophotometer). The data were analyzed using Manova statistical tests with LSD post hoc tests. From the observations, it was known that the addition of rumen liquor had a significant effect on the levels of P with the most optimal concentration of 50%, while for N and K levels and Pb heavy metals content was not significantly different. However, the average level of nutrient elements N (0.87% to 1.1%), P (0.2% to 0.5%) and K (0.52% to 0.58%) and Pb heavy metals (0.61ppm to 4.09 ppm) fulfill SNI 19-7030- 2004 standard.
